CAMEL mainly uses context summarization in three approaches:

1. ContextSummarizerToolkit, which enables the agent to clean the context by itself.
2. Manual API agent.summmarize() which can be called by the developer.
3. tokenlimit automatic context summarization when context is getting filled feat: summarize when tokenlimit exceeded or threshold reached #3227

the goal of this issue is to make sure the backend summarization approaches are as unified and consistent as possible. this includes the summarization logic, the prompts, etc.
